Available on Windows only.
Expand description

An owned handle.

This closes the handle on drop.

Note that it may have the value -1, which in OwnedHandle always represents a valid handle value, such as the current process handle, and not INVALID_HANDLE_VALUE, despite the two having the same value. See here for the full story.

And, it may have the value NULL (0), which can occur when consoles are detached from processes, or when windows_subsystem is used.

OwnedHandle uses CloseHandle to close its handle on drop. As such, it must not be used with handles to open registry keys which need to be closed with RegCloseKey instead.

Implementations
